Earlier men used to carry their luggage on their head and in hands. But later on the invention of wheels and cark changes everything. But later on men invented bridges and stairs. The problem again remain same because wheels can’t move on the stairs. Later on man invented some mechanism to climb on the stairs. But in that there are certain problems such that sometimes the surface was not exactly flat and the shaft would rotate. And sometimes while pulling on the stairs trolley would slip. In order to remove that problem we think and apply mechanism in that trolley. We apply the mechanism use in cycles so that it will not slip back on the stairs and a breaking system which will hold the wheel and shaft in its position when it is moving on the flat surface to avoid the problem of slippage.
